This is a replacement housing for use with a 12vdc 433mhz relay controller. The supplied case that comes with the module barely has room for the module and trying to cram wires into the case is messy. I drew up two versions - one with screw holes for mounting the other without screw holes for use with double-sided tape. the wiring can be secured with zip ties. there is a slot in the body of the housing giving access to the programming switch for the relay module.
